RESUMEN
OBJECTIVE: Lipedema is a chronic and progressive disease associated with lymphatic impairment at later stages. The aim of our study was to describe the functional status and anatomy of lower limb superficial lymphatic system using indocyanine green (ICG) lymphography in patients with lipedema. METHODS: Following ICG injection at the dorsum of the foot, distance (cm) covered by the dye at 10 (T10') and 25 min (T25') was measured and normalized for limb length. If the dye did not reach the groin within 25 min, patients were classified as "drainage-needing" group (DNG). Values of fat and lean distribution assessed by dual-energy X-ray absorptiometry were extracted, and correlation analysis was performed. Furthermore, anatomical patterns of superficial lymphatics were assessed. RESULTS: Overall, 45 women were included, 25 (56%) of whom were classified as DNG. Symptoms duration was significantly associated with DNG status at multivariate analysis (odds ratio 1.07; 95% CI 1.01-1.14; p = 0.047). Moreover, Spearman's analysis showed a negative correlation between symptoms duration and T25' dye migration (r = -0.469; p = 0.037). Overall, no major anatomical lymphatic changes were found. CONCLUSIONS: Present study suggests that lymphatic functioning in patients with lipedema correlates with symptoms duration. Further research on larger cohorts should verify our findings and clarify their potential therapeutic implications. Overall, ICG lymphography may be promising technique to assess both lymphatic anatomy and functioning in patients with lipedema.

Resumen El lipedema es una enfermedad común, frecuentemente subdiagnosticada, crónica y progresiva, que genera un gran deterioro en la calidad de vida. Consiste en el depósito anormal de tejido adiposo subcutáneo principalmente en las extremidades inferiores, afectando casi exclusivamente a mujeres. Sus síntomas principales son el dolor, la sensibilidad y la facilidad para producir equimosis. Desde el punto de vista fisiopatológico, existiría una susceptibilidad poligénica combinada con trastornos hormonales, microvasculares y linfáticos que pueden ser en parte responsables del desarrollo del lipedema. Se clasifica, según la distribución de la grasa en cinco tipos y, según la gravedad de la enfermedad, en cuatro etapas. El diagnóstico es eminentemente clínico y se debe diferenciar de otras patologías que producen aumento de volumen de las extremidades, especialmente el linfedema y obesidad. Es importante realizar un estudio funcional del sistema linfático cuando el diagnóstico es dudoso o para la etapificación del lipedema, por lo que la correcta interpretación de estos resultados es fundamental. El tratamiento está enfocado en disminuir la discapacidad y evitar la progresión, con el fin de mejorar la calidad de vida. Actualmente, la liposucción es un tratamiento efectivo para el lipedema, sin embargo, las técnicas empleadas para la lipectomía en el lipedema son diferentes a las técnicas utilizadas para la liposucción con fines estéticos. Las técnicas selectivas que respetan los vasos linfáticos tienen mejor rendimiento para reducir el volumen de grasa, retrasar la progresión, reducir el dolor, reducir la alteración marcha y mejorar la calidad de vida en estos pacientes.
Lipedema is a common, frequently under-diagnosed, chronic and progressive disease that generates an important detriment in quality of life. It consists in an abnormal deposit of subcutaneous adipose tissue mainly in the lower extremities, almost exclusively affecting women. Its main symptoms are pain, sensitivity and the ease of causing bruising. From the pathophysiological point of view, there would be a polygenic susceptibility combined with hormonal, microvascular and lymphatic disorders that may be partly responsible for the development of lipedema. It is classified according to the distribution of fat into five types and, according to the severity of the disease, in four stages. The diagnosis is eminently clinical and must be differentiated from other diseases that cause an increase in the volume of the extremities, especially lymphedema and obesity. It is important to carry out a study of the lymphatic system functionality when the diagnosis is not clear or for lipedema staging, so the correct interpretation of these results is essential. Treatment is focused on reducing disability and preventing progression, in order to improve quality of life. Liposuction is currently an effective treatment for lipedema, however, the techniques used for lipectomy in lipedema are different from the techniques used for liposuction for cosmetic purposes. Selective techniques that spare the lymphatic vessels have better results reducing fat volume, delaying progression, reducing pain, reducing gait disturbance, and improving quality of life of these patients.

BACKGROUND/OBJECTIVES: Patients with obesity and lipedema commonly are misdiagnosed as having lymphedema. The conditions share phenotypic overlap and can influence each other. The purpose of this study was to delineate obesity-induced lymphedema, obesity without lymphedema, and lipedema in order to improve their diagnosis and treatment. SUBJECTS/METHODS: Our Lymphedema Center database of 700 patients was searched for patients with obesity-induced lymphedema (OIL), obesity without lymphedema (OWL), and lipedema. Patient age, sex, diagnosis, cellulitis history, body mass index (BMI), and treatment were recorded. Only subjects with lymphoscintigraphic documentation of their lymphatic function were included. RESULTS: Ninety-eight patients met inclusion criteria. Subjects with abnormal lymphatic function (n = 46) had a greater BMI (65 ± 12) and cellulitis history (n = 30, 65%) compared to individuals with normal lymphatic function [(BMI 42 ± 10); (cellulitis n = 8, 15%)] (p < 0.001). Seventeen patients had a history of lipedema and two exhibited abnormal lymphatic function (BMI 45, 54). The risk of having lower extremity lymphedema was predicted by BMI: BMI < 40 (0%), 40-49 (17%), 50-59 (63%), 60-69 (86%), 70-79 (91%), ≥80 (100%). Five patients with OIL (11%) underwent resection of massive localized lymphedema (MLL) or suction-assisted lipectomy. Three individuals (18%) with lipedema were treated with suction-assisted lipectomy. CONCLUSIONS: The risk of lymphedema in patients with obesity and lipedema can be predicted by BMI; confirmation requires lymphoscintigraphy. Individuals with OIL are at risk for cellulitis and MLL. Patients with a BMI > 40 are first managed with weight loss. Excisional procedures can further reduce extremity size once BMI has been lowered.

BACKGROUND: Lipedema is often unrecognized or misdiagnosed; despite an estimated prevalence of 10% in the overall female population, its cause is still unknown. There is increasing awareness of this condition, but its differential diagnosis can still be challenging. In this article, we summarize current hypotheses on its pathogenesis and the recommendations of current guidelines for its diagnosis and treatment. METHODS: This review is based on publications about lipedema that were retrieved by a selective search in the MEDLINE, Web of Science, and Cochrane Library databases. RESULTS: The pathophysiology of lipedema remains unclear. The putative causes that have been proposed include altered adipogenesis, microangiopathy, and disturbed lymphatic microcirculation. No specific biomarker has yet been found, and the diagnosis is currently made on clinical grounds alone. Ancillary tests are used only to rule out competing diagnoses. The state of the evidence on treatment is poor. Treatment generally consists of complex decongestive therapy. In observational studies, liposuction for the permanent reduction of adipose tissue has been found to relieve symptoms to a significant extent, with only rare complications. The statutory healthinsurance carriers in Germany do not yet regularly cover the cost of the procedure; studies of high methodological quality will be needed before this is the case. CONCLUSION: The diagnosis of lipedema remains a challenge because of the hetero - geneous presentation of the condition and the current lack of objective measuring instruments to characterize it. This review provides a guide to its diagnosis and treatment in an interdisciplinary setting. Research in this area should focus on the elucidation of the pathophysiology of lipedema and the development of a specific biomarker for it.

Genetic or acquired defects of the lymphatic vasculature often result in disfiguring, disabling, and, occasionally, life-threatening clinical consequences. Advanced forms of lymphedema are readily diagnosed clinically, but more subtle presentations often require invasive imaging or other technologies for a conclusive diagnosis. On the other hand, lipedema, a chronic lymphatic microvascular disease with pathological accumulation of subcutaneous adipose tissue, is often misdiagnosed as obesity or lymphedema; currently there are no biomarkers or imaging criteria available for a conclusive diagnosis. Recent evidence suggests that otherwise-asymptomatic defective lymphatic vasculature likely contributes to an array of other pathologies, including obesity, inflammatory bowel disease, and neurological disorders. Accordingly, identification of biomarkers of lymphatic malfunction will provide a valuable resource for the diagnosis and clinical differentiation of lymphedema, lipedema, obesity, and other potential lymphatic pathologies. In this paper, we profiled and compared blood plasma exosomes isolated from mouse models and from human subjects with and without symptomatic lymphatic pathologies. We identified platelet factor 4 (PF4/CXCL4) as a biomarker that could be used to diagnose lymphatic vasculature dysfunction. Furthermore, we determined that PF4 levels in circulating blood plasma exosomes were also elevated in patients with lipedema, supporting current claims arguing that at least some of the underlying attributes of this disease are also the consequence of lymphatic defects.

Lipedema is a lymphedema-masquerading symmetrical, bilateral and disproportional obesity. Its conservative maintenance treatment comprises the use of flat-knitted compression pantyhoses. Lipedema is known to be associated with left ventricular morphological and functional alterations. The present study aimed to assess the effects of graduated compression stockings on left ventricular (LV) rotational mechanics measured by three-dimensional speckle-tracking echocardiography (3DSTE) in lipedema patients. The present study comprised twenty lipedema patients (mean age: 45.8 ± 11.0 years, all females) undergoing 3DSTE who were also compared to 51 age- and gender-matched healthy controls (mean age: 39.8 ± 14.1 years, all females). 3DSTE analysis was performed at rest, and subsequent to 1 hour application of compression class 2 made-to-measure flat-knitted pantyhose. Six lipedema patients showed significant LV rotational abnormalities. Of the remaining fourteen lipedema patients LV basal rotation rotation showed significant reduction, while LV apical rotation showed significant increase with unchanged LV twist after a 60-minute use of compression garment. Significant changes in LV rotational mechanics could be detected among 14 women with lipedema after the use of compression garment however six probands have special LV rotational abnormalities at baseline and/or after compression.

OBJECTIVE: Lipedema is characterized by pain, fatigue, and excessive adipose tissue and sodium accumulation of the lower extremities. This case-control study aims to determine whether sodium or vascular dysfunction is present in the central nervous system. METHODS: Brain magnetic resonance imaging was performed at 3 T in patients with lipedema (n = 15) and control (n = 18) participants matched for sex, age, race, and BMI. Standard anatomical imaging and intracranial angiography were applied to evaluate brain volume and vasculopathy, respectively; arterial spin labeling and sodium magnetic resonance imaging were applied to quantify cerebral blood flow (CBF) (milliliters per 100 grams of tissue/minute) and brain tissue sodium content (millimoles per liter), respectively. A Mann-Whitney U test (significance criteria P < 0.05) was applied to evaluate group differences. RESULTS: No differences in tissue volume, white matter hyperintensities, intracranial vasculopathy, or tissue sodium content were observed between groups. Gray matter CBF was elevated (P = 0.03) in patients with lipedema (57.2 ± 9.6 mL per 100 g/min) versus control participants (49.8 ± 9.1 mL per 100 g/min). CONCLUSIONS: Findings provide evidence that brain sodium and tissue fractions are similar between patients with lipedema and control participants and that patients with lipedema do not exhibit abnormal radiological indicators of intracranial vasculopathy or ischemic injury. Potential explanations for elevated CBF are discussed in the context of the growing literature on lipedema symptomatology and vascular dysfunction.

PURPOSE: Lipedema is a chronic, common but underdiagnosed disease masquerading obesity, with female predominance, characterized by disproportional abnormal adipose tissue distribution of the lower and also upper extremities. The present study was designed to determine whether lipedema is associated with three-dimensional (3D) speckle-tracking echocardiography (3DSTE)-derived left ventricular (LV) deformation abnormalities, and to assess the effects of 1-hour use of medical compression stockings (MCS). METHODS: The present study comprised 19 female patients with lipedema (mean age: 42.2 ± 12.4 years), compared to 28 age-matched healthy female controls (mean age: 42.0 ± 9.8 years). RESULTS: Lipedema patients showed larger left atrial and LV dimensions and greater LV ejection fraction than controls, without significant difference in other echocardiography variables. Lipedema patients had greater 3DSTE-derived global and mean segmental LV circumferential and area strains than controls. Following 1-hour use of wearing MCS, neither global and nor mean segmental LV strains showed significant impairment or improvement. CONCLUSIONS: Increased LV strains could be compensatory effects maintaining LV pumping function in lipedema. Short-term wearing of MCS has no global effect on LV strains.

Lipedema is a fat disorder that is often misdiagnosed. It was first identified at the Mayo Clinic in 1940, but medical schools do not include it in their curriculum and is therefore poorly understood. It presents as disproportionate and symmetrical accumulations of fat (bilateral), which is often accompanied by orthostatic edema. Early diagnosis and treatment are crucial, as the disease is progressive and can lead to immobility as well as a significant decrease in the quality of life. Lipedema differs from obesity because it does not respond to diet and exercise. This article gives you a glimpse into what lipedema is about and will help you identify some differences between lipedema and lymphedema. It will also help you identify which surgical procedures have been successful in treating the disease.

BACKGROUND: Lower extremity lymphedema is frequently encountered in the vascular clinic. Established dogma purports that cancer is the most common cause of lower extremity lymphedema in Western countries, whereas chronic venous insufficiency (CVI) is often overlooked as a potential cause. Moreover, lymphedema is typically ascribed to a single cause, yet multiple causes can coexist. METHODS: A 3-year retrospective analysis was conducted of demographic and clinical characteristics of 440 eligible patients with lower extremity lymphedema who presented for lymphatic physiotherapy to a university medical center's cancer-based physical therapy department. RESULTS: The four most common causes of lower extremity lymphedema were CVI (phlebolymphedema; 41.8%), cancer-related lymphedema (33.9%), primary lymphedema (12.5%), and lipedema with secondary lymphedema (11.8%). The collective cohort was more likely to be female (71.1%; P < .0001), to be white (78.9%; P < .0001), to demonstrate bilateral distribution (74.5%; P < .0001), and to have involvement of the left leg (bilateral, 69.1% [P < .0001]; unilateral, 58.9% [P = .0588]). Morbid obesity was pervasive (mean weight and body mass index, 115.8 kg and 40.2 kg/m2, respectively) and significantly correlated with a higher International Society of Lymphology lymphedema stage (stage III mean weight and body mass index, 169.2 kg and 57.3 kg/m2, respectively, vs stage II, 107.8 kg and 37.5 kg/m2, respectively; P < .0001). Approximately one in three (35.7%) of the population sustained one or more episodes of cellulitis, but patients with stage III lymphedema had roughly twice the rate of soft tissue infection as patients with stage II, 61.7% vs 31.8%, respectively (P < .001). Multifactorial lymphedema was present in 25%. Approximately half of the patients with lipedema with secondary lymphedema (48.1%) or primary lymphedema (45.5%) had a superimposed cause of swelling that was usually CVI. Total knee arthroplasty was the most common cause of noncancer surgery-mediated worsening of pre-existing lymphedema. CONCLUSIONS: In a large cohort of patients treated in a cancer-affiliated physical therapy department, CVI (phlebolymphedema), not cancer, was the predominant cause of lower extremity lymphedema. One in four patients had more than one cause of lymphedema. Notable clinical characteristics included a proclivity for female patients, bilateral distribution, left limb, cellulitis, and nearly universal morbid obesity.

INTRODUCTION: Lipedema is a barely recognized and poorly diagnosed, but common disease affecting almost exclusively female patients. The pathomechanism of lipedema is not known, and clinically, it is a bilateral, symmetrical, disproportional fatty enlargement of the lower half of the body, the disease does not affect the feet, and the upper extremities are often involved. Since lipedema is associated with increased aortic stiffness and altered left ventricular (LV) rotational mechanics, the present study was designed to compare the size and function of the mitral annulus (MA) between lipedema patients and controls by three-dimensional speckle-tracking echocardiography (3DSTE). METHODS: Twenty-four patients with stage 2 lipedema and 48 age-, gender-, and body mass index-matched healthy control patients were included in the study. Each person from the lipedema and the control groups underwent two-dimensional Doppler echocardiography and 3DSTE. RESULTS: Significantly enlarged left atrial diameter, LV end-diastolic diameter and volume, and LV end-systolic volume could be detected in lipedema patients as compared to controls. None of the lipedema patients and controls showed ≥grade 1 mitral or tricuspid regurgitation. Dilated end-systolic and end-diastolic MA diameter, area, and perimeter could be demonstrated in lipedema patients as compared to controls, and these changes were accompanied by impaired MA fractional area change at rest. Following 1-hour use of compression stockings, no significant improvement was seen in these parameters. CONCLUSIONS: Lipedema is associated with MA enlargement and functional impairment. The use of compression stockings does not improve these alterations.

Background and Aim: Lipedema is a common painful SAT disorder characterized by enlargement of fat primarily in the legs of women. Case reports of lipedema tissue samples demonstrate fluid and fibrosis in the interstitial matrix, increased macrophages, and adipocyte hypertrophy. The aims of this project are to investigate blood vasculature, immune cells, and structure of lipedema tissue in a cohort of women. Methods: Forty-nine participants, 19 controls and 30 with lipedema, were divided into groups based on body mass index (BMI): Non-Obese (BMI 20 to <30 kg/m2) and Obese (BMI 30 to <40 kg/m2). Histological sections from thigh skin and fat were stained with H&E. Adipocyte area and blood vessel size and number were quantified using ImageJ software. Markers for macrophages (CD68), mast cells (CD117), T cells (CD3), endothelial cells (CD31), blood (SMA), and lymphatic (D2-40 and Lyve-1) vessels were investigated by IHC and IF. Results: Non-Obese Lipedema adipocyte area was larger than Non-Obese Controls (p=0.005) and similar to Obese Lipedema and Obese Controls. Macrophage numbers were significantly increased in Non-Obese (p < 0.005) and Obese (p < 0.05) Lipedema skin and fat compared to Control groups. No differences in T lymphocytes or mast cells were observed when comparing Lipedema to Control in both groups. SMA staining revealed increased dermal vessels in Non-Obese Lipedema patients (p < 0.001) compared to Non-Obese Controls. Lyve-1 and D2-40 staining showed a significant increase in lymphatic vessel area but not in number or perimeter in Obese Lipedema participants (p < 0.05) compared to Controls (Obese and Non-Obese). Areas of angiogenesis were found in the fat in 30% of lipedema participants but not controls. Conclusion: Hypertrophic adipocytes, increased numbers of macrophages and blood vessels, and dilation of capillaries in thigh tissue of non-obese women with lipedema suggest inflammation, and angiogenesis occurs independent of obesity and demonstrates a role of altered vasculature in the manifestation of the disease.

Unilateral lower extremity edema below the knee commonly results from deep venous thrombosis, venous insufficiency, or lymphedema. The patient history, a physical examination, and lower extremity venous duplex ultrasound often reveal the underlying etiology, which is frequently of vascular origin. Presently described is the case of a 23-year-old patient who underwent a diagnostic workup for unilateral leg swelling and was found to have a relatively uncommon cause of edema: lipedema. Lipedema is a disease characterized by subcutaneous adipose tissue deposition, and although diagnosed very rarely in general cardiology outpatient clinics, it has been demonstrated to be a cause of lower extremity edema in approximately one-fifth of cases in specialized clinics.

Lipedema, the Unknown Abstract. Lipoedema patients suffer from the widespread ignorance of their pathology. Considering its chronic, progressive and invalidating character, the early diagnosis of the disease must constitute the challenge of their caregivers in order to limit medical wanderings and the occurrence of complex clinical pictures. Treatments allow the reduction of lipedema and its long-term control. Management must be individualized according to the stage of the disease. The adherence of the patient, the supervision and the support of the practitioner are essential for obtaining the best results.

Lipedema: Which Etiological Pathways? Abstract. The pathogenesis and epidemiology of lipedema are uncertain, and its diagnosis often delayed. Lipedema almost exclusively affects women, and a link to sex hormones is likely. The metabolic risk of this accumulation of fat in the lower limbs is not known, and weight loss has no impact on the morphology of the lower limbs. Due to the aesthetic discomfort and frequent initial misdiagnosis which results in inappropriate treatment, this condition can lead to significant psychological suffering for the patient. A better understanding of this disease is essential to the proper diagnosis and support for these patients, as well as guiding them in the effective care.

Lipoedema is painful nodular subcutaneous adipose tissue (SAT) on legs and arms of women sparing the trunk. People with Dercum disease (DD) have painful SAT masses. Lipoedema and DD fat resists loss by diet and exercise. Treatments other than surgery are needed. Six women with lipoedema and one with DD underwent twelve 90-min sessions over 4 weeks. Body composition by dual X-ray absorptiometry scan, leg volume, weight, pain, bioimpedance, tissue size by caliper and ultrasound were analysed before and after SAT therapy by paired t-tests. There was a significant decrease from baseline to end of treatment in weight, 87.6 ± 21 to 86.1 ± 20.5 kg (P = 0.03), leg fat mass 17.8 ± 7.7 to 17.4 ± 7.6 kg (P = 0.008), total leg volume 12.9 ± 4 to 12 ± 3.5 L (P = 0.007), six of 20 calliper sites and tissue oedema. Pain scores did not change significantly. By ultrasound, six women had 22 hyperechoic masses in leg fat that resolved after treatment; five women developed seven new masses. Fascia improved by ultrasound after treatment. SAT therapy reduced amount and structure of fat in women with lipoedema and Dercum disease; studies are needed to compare SAT therapy to other therapies.

Lipoedema is a rare painful disorder of the adipose tissue. It essentially affects females and is often misdiagnosed as lymphoedema or obesity. It is globally misdiagnosed or underdiagnosed, and the literature is lacking appropriate guidance to assist clinicians towards this diagnosis. However, the need to recognise this disorder as a unique entity has important implications to establish proper treatment and, therefore, its tremendous effect on patients. Early diagnosis and treatment can turn these patients' lives upside down. The aim of this review is to focus on the clinical guidance, differential diagnosis, and management strategies. In addition, other aspects of lipoedema, including epidemiology and pathogenesis, are also being discussed here. Lipoedema is distinct from obesity and distinct from lymphoedema, although it might progress to involve the venous and lymphatic system (venolipedema or lympholipedema or both). Late diagnosis can leave the patient debilitated. Management of lipoedema includes weight loss, control of oedema, complex decongestive physiotherapy, liposuction, and laser-assisted lipolysis. However; there are increasing reports on tumescent liposuction as the preferred surgical option with long-lasting results. The role of more randomised controlled studies to further explore the management of this clinical entity remains promising.

Lipedema is a chronic, progressive adipose tissue disorder that may impact the quality of life of women who suffer from it. The main aim of this study was to asses the role of perceived symptom severity, physical and psychological functioning with the disease in predicting quality of life in patients with lipedema. We conducted an online study with 329 participants who responded to five questionnaires measuring quality of life (World Health Organization Quality of Life BREF), lipedema symptom severity, mobility (Lower Extremity Functional Scale), depression (Patients Health Questionnaire-9), and appearance-related distress (Derriford Appearance Scale 24). Multiple hierarchical regression analyses showed that appearance-related distress and depression explained significantly more variance in quality of life when added to the symptom severity and mobility. Lower quality of life was predicted by higher symptom severity, lower mobility, higher appearance-related distress and higher depression severity. Appearance-related distress and depression constitute important aspects of psychological functioning in women with lipedema. Considering their relationship with quality of life, their assessment should be included in lipedema treatment with appropriate interventions aimed at decreasing appearance-related distress, as well as preventing and addressing depression.

Lipedema an often overlooked but treatable disease Lipedema is a painful disease that affects some women between puberty and menopause through a subcutaneous fat accumulation especially in the lower extremities. Patients suffer from pain and pressure tenderness. The larger fat accumulation, especially on the inside of the thighs and knees, causes walking difficulties. This can successfully be treated by liposuction with good long-term results in terms of pain reduction and prevention of osteoarthritis development in the knee and ankle joints.

Lipedema is a common, but often underdiagnosed masquerading disease of obesity, which almost exclusively affects females. There are many debates regarding the diagnosis as well as the treatment strategies of the disease. The clinical diagnosis is relatively simple, however, knowledge regarding the pathomechanism is less than limited and curative therapy does not exist at all demanding an urgent need for extensive research. According to our hypothesis, lipedema is an estrogen-regulated polygenetic disease, which manifests in parallel with feminine hormonal changes and leads to vasculo- and lymphangiopathy. Inflammation of the peripheral nerves and sympathetic innervation abnormalities of the subcutaneous adipose tissue also involving estrogen may be responsible for neuropathy. Adipocyte hyperproliferation is likely to be a secondary phenomenon maintaining a vicious cycle. Herein, the relevant articles are reviewed from 1913 until now and discussed in context of the most likely mechanisms leading to the disease, which could serve as a starting point for further research.
